As a seasoned Brain Fertilizer, I'm often asked: "What is the secret to properly fertilizing one's brain?" Well, my friends, it's quite simple really. You see, the key is to find the right balance between the stimulating effects of Subrule 2: The Fertilizing Spectrum and the soothing effects of Subrule 3: The Fertilizing Frequency. Anything less and you're just wasting your time. Anything more and you're risking a nasty case of Subrule 4: The Fertilizing Overload.
Now, I know what you're thinking: "But what about Subrule 5: The Fertilizing Connoisseur?" Ah, yes, that's a whole different story altogether. That's for the advanced Brain Fertilizer looking to really get their hands dirty.
